Any Insight As To How This Happened?

[RanceEric]

Hi all,

I developed two rolls of Tri-x in D-76 last night that I shot at 400. The entire first roll and most of the second look great, just the last three frames on the second roll had large black lines through them.. Here's an example:

Any idea what may have caused this? I thought I loaded the reel all the way.. Anyone else have a similar issue before? There's probaby a simple explanation.. I just don't know it

Is it 120?

Is it 120?

Oops, forgot that part.. No, it's 35mm

Is it just the one frame? Or the whole roll?

Developed two rolls in the same tank, but it's only the last three or four frames on one of the rolls

Does is pass through the image and stop at the edges of your negative or continue onto the sprocket holes? If it stops at the edges of your image, most likely flare.

If it continues I have no clue.

 

[robbeiflex]

Are they all similar composition and lighting? If so, then flare would be my guess.

Cheers,

I would say flare, too. Or maybe you had a slight gap in your shutter curtain (if it travels horizontally, vertically wouldn't have that issue). Or maybe there was a slight gap in the dust trap on the roll and some light leaked in?

Those are the only things I can think of.

They do continue to the sprocket holes.. 😕

I thought that might be the case also, but I had a huge lens hood on at the time.. and there are other shots taken at very similar angles and the same lighting with no flare at all

other frames from the same roll:

If they do continue to the sprocket holes then it's not flare. I would guess gap in the dust trap on the roll and some light leaked in as mattewm suggests. Can you post them in the order they were on the roll?

That is a possibility.. the strips were BLACK.. so some kindof light leak makes sense. Just seemed off with the spacing between them (they were all in almost the exact same spot on each from, but varying thickness)


..... I guess it's just an unexplainable, freak accident...

I have messed up the last few frames a couple of times by not getting the film all the way onto the reel, and then having the film (I think) get caught/mangled when I put it in the tank. You expressed some uncertainty as to whether or not you really got it loaded correctly?

I like the photos by the way, sorry some got ruined. I can sympathize.

Not all are uploaded online, but I can upload them later tonight and post them in order.

Thanks everyone for trying to help me figure this out..

I agree to Randy. This happens when I don't load 120 films properly (they are more critical in loading than 35mm film).

Well, I was thinking maybe the end got stuck to the side of the tank and just wasn't exposed to the developer? but I'm pretty sure I didn't have the end sticking out of the reel.. but I could be wrong

I just found it strange.. In the many, many years on developing my own film.. 4 years is a long time! lol J/K.. I've never had this happen before

Thank you! 🙂

The fear of not being able to load the film correctly onto the reel is the only reason I haven't developed my own b&w 120 film.. ha..

Hello,

Was film bulk loaded or factory loaded? I sometimes fog one of two frames at the end when I bulk load. Guess my loading technique need improvement.

Factory loaded..

side note: I actually have wanted to try bulk loading myself.. might actually try that sometime soon..

Affected frames, in order:

Could you have bent the film? I know I ruined a few shots when the film got stuck when I was loading once (old paterson plastic reel that was TERRIBLE). I crinkled the film there. I forget if it ended up putting black lines on the film or white but it was a similar effect
